Description

Technical Field

[0001] The present invention relates to the technical field of candle combustion performance detection, and particularly relates to a candle combustion detection device and a detection method. Background Art

[0002] With the improvement of the market's requirements for candle quality, accurately detecting various physical parameters during the candle combustion process has become a key link in production quality control and technological research and development. However, the existing detection technologies face the following prominent problems in practical applications:

[0003] On the one hand, the cleaning efficiency of combustion residues is low: The wax oil generated after the candle burns is easily condensed and attached to the placement device, and it is necessary to manually disassemble the components for cleaning, which is cumbersome and time-consuming; at the same time, the glass plate for detecting the flue gas adsorption amount needs to be manually cleaned one by one. If the cleaning is not thorough, it is easy to cause deviation of the detection data before and after, affecting the accuracy of the results.

[0004] On the other hand, the environmental simulation function is limited: The existing detection devices can only provide fixed ventilation conditions such as single-direction air flow or natural convection, and cannot dynamically adjust the air flow angle such as horizontal, diagonal, vertical upward, etc. and the wind speed, making it difficult to reproduce the influence of diverse scenarios such as indoor door and window ventilation and outdoor natural wind on candle combustion, resulting in insufficient relevance between the detection data and the actual usage scenarios.

[0005] Taking the patent with the publication number CN211318337U as an example, the candle combustion flue gas detection device disclosed therein separates two detection spaces through a partition in the combustion chamber, and uses a slidable first limiting rod and a second limiting rod to respectively install wire mesh cylinders with different diameters. The diameter of the first wire mesh cylinder is smaller than that of the second wire mesh cylinder to achieve the simultaneous combustion of candles of different sizes. After the flue gas generated by combustion is adsorbed on the glass plate on the limiting rod, the light intensity difference between the clean glass and the glass with adsorbed flue gas is compared by a light intensity detector in the detection chamber to quantify the flue gas volume. However, this device still has the following defects:

[0006] 1. Lack of automatic cleaning: The device does not have an automatic wax oil collection and automatic glass plate cleaning function. After each detection, it is necessary to manually wipe the glass plate and manually clean the combustion residues. The single detection cycle is more than 5 minutes long, making it difficult to meet the batch detection requirements.

[0007] 2. Single air flow control: Only the top fan is used to accelerate the air circulation, and the air flow direction and speed cannot be accurately adjusted. The influence of different ventilation environments on the candle combustion rate and flue gas flow direction cannot be simulated, limiting the comprehensive analysis of the candle combustion characteristics.

[0008] Therefore, in view of the above statements, there is still room for optimization in the existing technologies for candle combustion detection. Summary of the Invention

[0017] Preferably, a resistance component for driving the sliding shaft to slide is provided in the rectangular plate, and the resistance component includes a structural groove opened in the rectangular plate and intersecting with the sliding groove. Two pushing plates passing through the structural groove and located at the upper and lower ends of the rectangular plate are symmetrically provided on the outer side of the sliding shaft. A triangular resistance plate is provided on the pushing plate, and the two resistance plates are oriented in opposite directions.

[0018] Preferably, a sleeve 1 is sleeved on the outer side of the screw rod, and the outer side corresponds to the lower end contact plate. Washers are rotated inside the sleeve 1 and on the lower end of the rectangular plate, and return springs are installed between the washers.

[0019] A sleeve 2 with an inner diameter corresponding to the upper end contact plate is sleeved on the outer side of the screw rod.

[0020] Preferably, an insertion member for installing and disassembling a glass slide is sleeved outside the rotating shaft. The insertion member includes several insertion slots opened on the outside of the rotating shaft. An insertion plate is inserted into the insertion slot in a detachable manner. A swing shaft is rotatably arranged on the insertion plate, and the glass slide is installed on the swing shaft.

[0021] Preferably, a transverse plate is installed on the inner side wall of the circular cavity. A wiping block that contacts the end face of one side of the glass slide is arranged on the transverse plate, and an installation slot is opened on one side of the rectangular block.

[0022] In addition, the present invention also provides a method for detecting candle burning, including the following steps:

[0023] S1, Candle installation: Light the candle and install it on the installation component, and then the pushing component pushes the supporting plate to move into the main body.

[0024] S2, Light detection: The external air pump extracts the gas in the main body through the circular groove, and the gas enters through the air inlet groove, so that the candle has sufficient oxygen to burn and the smoke generated by combustion is discharged from the circular groove. The smoke will not adhere to the glass slide, so that the visual detection device can detect the brightness of the candle flame through the clean glass slide.

[0025] S3, Smoke adhesion: The external air pump extracts the gas in the main body through the through groove, so that the gas passes through and adheres to the glass slide. Subsequently, the tester detects the substances generated by the candle burning through the gas remaining on the glass slide.

[0026] S4, Sealing detection: The supporting plate continues to move upward, the air inlet groove no longer corresponds to the installation component, the external air pump is turned off, and the candle continues to burn through the residual gas in the main body to test the burning time of the candle.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] First, through the one-way transmission cooperation of the supporting plate with the ratchet member and the driving tooth, after the candle burns out, when the supporting plate descends, the meshing characteristic of the ratchet member and the driving tooth in the strip groove is used to automatically drive the transmission shaft to drive the swing plate to flip 180 degrees, realizing the rapid replacement of the upper and lower supporting seats. Without manually cleaning the wax oil in the supporting seat, the next candle can be directly installed, significantly improving the detection efficiency and reducing manual operation.

[0029] 2. The present invention adopts the linkage design of the air inlet groove, the circular cavity and the glass slide driven by the rotating shaft. The external vacuum pump can switch the airflow path through the circular groove or the through groove: when detecting the combustion brightness, the airflow enters the main body through the air inlet groove and is discharged through the circular groove to ensure the cleanliness of the glass slide, and the visual detection device can clearly monitor the flame brightness through the glass slide; when detecting the combustion products, the airflow guides the gas through the circular cavity through the through groove, so that the smoke and dust adhere to the glass slide, and cooperates with the rotating shaft to drive multiple groups of glass slides to rotate in a cycle, so as to realize independent sampling and analysis of different candle combustion products.

[0030] 3. The present invention uses the linkage structure of the screw, the conical block and the scraping thread. When the screw drives the support plate to rise, the scraping thread on the outside of the conical block and the scraping plate synchronously scrape off the solidified wax oil in the lower end support seat; at the same time, when the glass slide rotates with the rotating shaft and passes through the wiping block on the horizontal plate in the circular cavity, the wiping block automatically removes the attachments on the surface of the glass slide. The double cleaning mechanism ensures the cleanliness of the support seat and the detection interface, and prevents residual substances from affecting the subsequent detection accuracy.

[0045] The following combination Figures 1 to 12 Embodiments of the present invention are described in detail.

[0046] The embodiments of the present application disclose a candle combustion detection device and method for detecting the brightness, product composition and duration of combustion, and can automatically clean residues and replace candles; the device sends samples for combustion through a supporting structure, a movable supporting component and a pushing assembly, uses an air intake channel and a rotating transparent plate cavity to achieve airflow circulation and product detection, a visual device monitors the brightness, a one-way transmission changes the supporting position, a conical component scrapes off wax oil, and the transparent plate automatically cleans; the detection is divided into four steps: installing the candle into the main body, measuring the brightness with airflow to assist combustion, switching channels to sample components, and sealing with residual gas to measure the burning time.

[0047] Example 1: Reference Figure 1 , Figure 2 and Figure 3As shown in the figure, it includes a main body 1, support legs 10, a supporting plate 11, a mounting component 2, a rectangular plate 12, a pushing component 3, an air inlet groove 13, a rectangular block 14, a circular cavity 15, a sector-shaped groove 16, a rotating shaft 17, a glass slide 18, a visual detection device 19, a through groove 110 and a circular groove 111. There are several support legs 10 arranged below the main body 1. The lower end of the main body 1 is in a through shape. A supporting plate 11 slides between the support legs 10. A mounting component 2 for installing a candle is arranged on the supporting plate 11. When the supporting plate 11 is driven by an external force, it can drive the mounting component 2 to move into the main body 1.

[0048] A rectangular plate 12 is arranged between the support legs 10. A pushing component 3 for driving the supporting plate 11 to move up and down is arranged on the rectangular plate 12. The pushing component 3 can provide an upward force for the supporting plate 11.

[0049] An air inlet groove 13 is opened on one side of the main body 1.

[0050] A rectangular block 14 is arranged on one side of the main body 1. A circular cavity 15 is jointly opened in the rectangular block 14 and the main body 1. A sector-shaped groove 16 communicating with the circular cavity 15 is opened in the main body 1. A rotating shaft 17 rotates in the circular cavity 15. A glass slide 18 is arranged on the outer side of the rotating shaft 17. That is, the rotating shaft 17 can be driven to drive the glass slide 18 to rotate around its axis by connecting an external driving motor to one side of the rotating shaft 17. A visual detection device 19 is arranged in the circular cavity 15. When the candle is burning, the visual detection device 19 can detect and record the burning brightness of the candle through the glass to test the burning brightness of the candle. And the visual detection device 19 is an existing device. Its principle in this implementation process is only to test the brightness of the candle and enable the tester to monitor the burning situation of the candle in the main body 1 in real time through the camera at the end of the visual detection device 19. Therefore, it will not be elaborated in this implementation process.

[0051] A through groove 110 penetrating the inside of the main body 1 is jointly opened in the rectangular block 14 and the main body 1. And a circular groove 111 is also opened at the upper end of the main body 1. When the candle burns in the main body 1, air can enter the main body 1 through the air inlet groove 13, and the gas generated by the burning of the candle can be discharged out of the main body 1 through the circular cavity 15 or the circular groove 111, thus forming an air circulation.

[0052] Combined with the above implementation process, the present application also proposes a method for detecting candle burning, including the following steps:

[0053] S1, Candle installation: Light the candle and install it on the mounting component 2, and then the pushing component 3 pushes the supporting plate 11 to move into the main body 1.

[0054] S2, Light Detection: The external air pump extracts the gas inside the main body 1 through the circular groove 111, and the gas enters through the air inlet groove 13, enabling the candle to burn with sufficient oxygen and the flue gas generated by combustion to be discharged from the circular groove 111. The flue gas does not adhere to the glass slide 18, allowing the visual detection device 19 to detect the brightness of the candle flame through the clean glass slide 18.

[0055] S3, Flue Gas Adhesion: The external air pump extracts the gas inside the main body 1 through the through groove 110, causing the gas to pass through and adhere to the glass slide 18. Subsequently, the tester detects the substances generated by the candle combustion through the gas remaining on the glass slide 18.

[0056] S4, Sealing Detection: The supporting plate 11 continues to move upward, the air inlet groove 13 no longer corresponds to the mounting component 2, the external air pump is turned off, and the candle continues to burn through the residual gas inside the main body 1 to test the burning time of the candle.

[0057] Refer to Figure 4 and Figure 5 As shown, it is the mounting component 2 for installing the candle; specifically, the mounting component 2 includes a swing plate 20, a supporting seat 21, a strip groove 22, a transmission shaft 23, a ratchet member 24, a driving tooth 25, and a snap spring member 26. A rectangular groove is opened above the supporting plate 11, and a swing plate 20 rotates inside the rectangular groove. The upper and lower ends of the swing plate 20 are provided with supporting seats 21. First, insert the candle into the insertion seat at the upper end, and then light the candle. The supporting plate 11 moves upward so that the candle can burn inside the main body 1. After the candle burns out, the wax oil generated by the candle will drip into the supporting seat 21. At this time, the rectangular plate 12 descends, and the swing plate 20 is driven by an external force to rotate 180 degrees, and the upper and lower two supporting seats 21 will be swapped up and down. At this time, the tester can insert the next candle to be detected into the supporting seat 21 without cleaning the wax oil generated after the previous candle burns.

[0058] A strip groove 22 is opened on one side of the main body 1. A transmission shaft 23 whose one side is connected to the end of the swing plate 20 and the other side is located inside the strip groove 22 rotates through the supporting plate 11. A ratchet member 24 is sleeved on the outer side of the transmission shaft 23, and several driving teeth 25 corresponding to the ratchet member 24 are provided on the inner side wall of the strip groove 22.

[0059] That is, when the supporting plate 11 rises, it will drive the transmission shaft 23 and the ratchet member 24 to move into the strip-shaped groove 22. When the candle burns out, the supporting plate 11 can continue to rise, and the candle will not collide with the inner top wall of the main barrel. The ratchet member 24 will engage with the driving teeth 25 on the strip-shaped groove 22. However, at this time, the ratchet member 24 will not drive the transmission shaft 23 to rotate. Then the supporting plate 11 descends. At this time, through the one-way transmission characteristic of the ratchet member 24, the cooperation between the ratchet member 24 and the driving teeth 25 can flip the swing plate 20 by 180 degrees through the transmission shaft 23, achieving the effect of swapping the upper and lower supporting seats 21.

[0060] To make the transmission shaft 23 stable in the initial situation, a snap spring member 26 is installed in the supporting plate 11. The snap spring member 26 is a spring rod, and several clamping grooves are provided on the outer side of the transmission shaft 23. The spring rod abuts in the clamping grooves, playing a role of limiting and clamping the transmission shaft 23. The transmission shaft 23 will only rotate when the clamping force received by the transmission shaft 23 is greater than the clamping force of the spring rod, ensuring that the swing plate 20 will not flip in the initial state.

[0061] Refer to Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown in

[0062] That is, the sliding shaft 35 can drive the arc-shaped plate 36 to contact or not contact the thread on the outer side of the lead screw 30. When contact occurs, the lead screw 30 can be driven by an external force to move in the up and down directions in cooperation with the arc-shaped plate 36. When the sliding shaft 35 drives the arc-shaped plate 36 to no longer cooperate with the lead screw 30, the lead screw 30 will be driven by gravity to slide downwards.

[0063] During the process of the lead screw 30 rotating and rising, the lead screw 30 can drive the supporting plate 11 to rise through the contact and cooperation between the tapered block 31 and the inner wall of the lower supporting seat 21. And at this time, if there is dried wax oil in the lower supporting seat 21, the tapered block 31 can scrape off the wax oil in the supporting seat 21 through the scraping thread 32 and the scraping plate 33.

[0064] A retaining spring 26 is also installed in the rectangular plate 12, and a retaining groove is also opened on the outside of the sliding shaft 35, and the telescopic end of the spring rod is pressed in the retaining groove to limit the sliding shaft 35, so that in the initial situation, the sliding shaft 35 will not rotate when the screw rod 30 rotates, so that the screw rod 30 can achieve the effect of rotating in the up and down directions.

[0065] A driving ring 37 is also rotatably provided on the rectangular plate 12, and the inner diameter of the driving ring 37 is in keyway sliding fit with the screw rod 30. A driving shaft 38 is also rotatably provided on the rectangular plate 12, and the driving shaft 38 is connected to the driving ring 37 by belt transmission. The driving shaft 38 can be connected to the main shaft of an external driving motor so that it can be driven to rotate, and then the driving ring 37 is driven to rotate by the transmission. The driving ring 37 can drive the screw rod 30 to rotate by sliding in the keyway, and the screw rod 30 will not interfere with the driving ring 37 when moving up and down.

[0066] Continue to refer to Figure 8 and Figure 9 As shown, a resistance component 4 for driving the sliding shaft 35 to slide is provided in the rectangular plate 12; specifically, the resistance component 4 includes a structural groove 40, a push plate 41, a resistance plate 42, a sleeve 1 43, a gasket 44, a return spring 45 and a sleeve 2 46. The structural groove 40 is opened in the rectangular plate 12 and intersects with the sliding groove 34. Two pushing plates 41 passing through the structural groove 40 and located at the upper and lower ends of the rectangular plate 12 are symmetrically provided on the outer side of the sliding shaft 35. A triangular resistance plate 42 is provided on the pushing plate 41, and the two resistance plates 42 are in opposite directions. That is, when any one of the resistance plates 42 is driven by an external force, the sliding shaft 35 can be driven to move in the sliding groove 34 through the pushing plate 41.

[0067] A sleeve 43 is sleeved on the outside of the screw rod 30, and the outer side corresponds to the lower end contact plate 42. A gasket 44 is rotated inside the sleeve 43 and the lower end of the rectangular plate 12, and a return spring 45 is installed between the gaskets 44, that is, when the screw rod 30 moves up and down, it can drive the sleeve 43 to move and rotate synchronously. Therefore, when the screw rod 30 moves upward, it will drive the sleeve 43 to move synchronously, and in this process, the sleeve 43 will drive the return spring 45 to be compressed between the rectangular plates 12 through the gasket 44 inside it, and the rotation design of the two gaskets 44 is to prevent the rotation of the sleeve 43 from interfering with the return push spring, so that the return spring 45 and the sleeve 43 are movably connected.

[0068] When the lead screw 30 drives the first sleeve 43 close to the contact plate 42 at the lower end, that is, at this time the candle has burned out and the test has been completed. The lead screw 30 continues to move so that the outer side of the first sleeve 43 contacts the inclined surface of the contact plate 42, causing the contact plate 42 to drive the sliding shaft 35 to move away from the lead screw 30 through the push plate 41. As a result, the arc plate 36 is no longer threadedly connected to the lead screw 30, and at this time, the contracted return spring 45 releases the thrust to drive the lead screw 30 to quickly slide downwards in the reverse direction.

[0069] And the supporting plate 11 will also descend at this time, but the falling speed of the lead screw 30 driven by the return spring 45 is faster than that of the supporting plate 11. And at this time, the ratchet member 24 also contacts the driving tooth 25. Finally, the conical block 31 moves with the lead screw 30 and is no longer located in the supporting seat 21. The ratchet member 24 can drive the swing plate 20 to flip, so that the supporting seat 21 with wax oil at the upper end is driven to correspond to the lead screw 30. Then, when the lead screw 30 continues to move upwards next time, the wax oil in the supporting seat 21 can be scraped off by the scraping thread 32 or the scraping plate 33.

[0070] A second sleeve 46 with an inner diameter corresponding to the upper contact plate 42 is also sleeved outside the lead screw 30. That is, when the lead screw 30 moves, it will synchronously drive the second sleeve 46 to move. After the lead screw 30 slides, the inner diameter of the second sleeve 46 contacts the inclined surface of the upper contact plate 42, enabling the upper contact plate 42 to indirectly drive the arc plate 36 to move towards the lead screw 30 and be in threaded cooperation with the lead screw 30, so that the lead screw 30 can continue to move upwards. Further, the wax oil scraped off by the scraping thread 32 and the scraping plate 33 will also fall on the second sleeve 46, and the tester can clean it regularly.

[0071] Refer to Figure 10 、 Figure 11 and Figure 12 As shown in

[0072] That is, by inserting the insertion plate 50 into the insertion groove, the glass slide 18 can be limited outside the rotating shaft 17. Further, the glass slide 18 can also rotate under the drive of the swing shaft 51. The inner side wall of the sector-shaped groove 16 extends to a sealing plate that contacts the outside of the glass slide 18. The sealing plate is used to seal the gap around the glass slide 18. When the external air pump extracts the flue gas in the main body 1 through the through groove 110, the flue gas can contact the glass slide 18 and will not contact other glass slides 18 through the gap between the glass slide 18 and the sector-shaped groove 16, so that the soot in the flue gas adheres to the glass slide 18. Subsequently, the detection personnel can study and detect the components generated by the candle burning through the soot residue on the glass slide 18. During the detection process, when different candles are replaced, the rotating shaft 17 will also drive several glass slides 18 to rotate at this time, so that the next clean glass slide 18 corresponds to the sector-shaped groove 16.

[0073] A cross plate 52 is installed on the inner side wall of the circular cavity 15. A wiping block 53 that contacts the end face of one side of the glass slide 18 is arranged on the cross plate 52. An installation groove 54 is opened on one side of the rectangular block 14. When the rotating shaft 17 drives the glass slide 18 with adhered soot to move into the circular cavity 15, that is, when it is necessary to study the composition of the soot at this time, the detection port of the external detection device is docked with the installation groove 54, so that the detection port of the external detection device can correspond to one side of the glass slide 18 through the installation groove 54. At this time, the side of the glass slide 18 with adhered soot does not correspond to the installation groove 54. At this time, the glass slide 18 can be driven to rotate by the swing shaft 51 so that the adhered surface of the glass slide 18 corresponds to the detection port of the external detection device, so that the external detection device can directly detect the soot outside the glass.

[0074] During the continuous rotation of the rotating shaft 17, the side of the glass slide 18 with adhered soot will contact the wiping block 53. When the glass slide 18 moves, the wiping block 53 can wipe off the soot on the glass slide 18, making the glass slide 18 in a clean state.

[0075] Moreover, the detection personnel can also install or remove the insertion plate 50 in the insertion groove through the installation groove 54.

[0076] It should be noted that the "external detection device" mentioned in this embodiment is any detection device that can be used to detect candle soot. Its specific type is not limited in this embodiment.

[0077] Embodiment 2: Continue to refer to Figure 11 and Figure 12As shown, on the basis of the first embodiment, in order to be able to drive the swing shaft 51 to drive the glass slide 18 to turn over, so that the tester can detect the gas residues on the glass slide 18 through an external detection device, a driving assembly 6 is provided on the inner side wall of the main body 1; specifically, the driving assembly 6 includes a driving cavity 60, a driving gear 61, a support plate 62, a support shaft 63 and a fixed gear 64. The driving cavity 60 is opened inside the main cylinder. The swing shaft 51 passes through the corresponding insertion plate 50 and the outer wall of the rotating shaft 17 and is located inside the driving cavity 60. A driving gear 61 is sleeved on the outer side of the swing shaft 51 in the driving cavity 60. A support plate 62 is further provided on the inner side wall of the main body 1. One side of the support plate 62 is provided with a support shaft 63 extending into the driving cavity 60. The support plate 62 is used to support the support shaft 63.

[0078] A fixed gear 64 is sleeved on the outer side of the support shaft 63, and partial teeth are provided on the outer side of the fixed gear 64.
